<p class="para">
 对于所有变量运算函数，本函数的参数可以是 PHP
 内置的类型（整数，字符串，浮点数，布尔型或者
 <strong><code>NULL</code></strong>），或者是一个 COM，VARIANT 或者 DOTNET 类的实例。PHP
 内置类型将会使用和构造<a href="class.variant.html" class="xref">VARIANT</a>类相同的规则转换成变量。COM 和 DOTNET
 对象的值将会取其默认属性并被当成变量值使用。
</p>
<p class="para">
 变量运算函数是同名函数在 COM
 库中的外包；有关此类函数的更多信息参见 MSDN
 库。PHP 函数命名有少许区别，例如 PHP
 中的 <span class="function"><a href="variant_add.html" class="function">variant_add()</a></span> 对应于
 MSDN 文档中的 <em>VarAdd()</em>。
